7. = Ms. Liao runs a small dress company. From 1995 through 2005, the number of dresses she made can be modeled by N(X) = 0.3x2 – x 1.6x + 14, and the average cost to make each dress can be modeled by C(x) = -0.001x2 – 0.06x + 8.3, where x is the number of years C since 1995. Write a polynomial that can be used to model Ms. Liao's total dressmaking costs, T(x), for those years.

ian gone lie this got me confused

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
